ABSTRACT:
A radio communication system includes multiple communications nodes which may become diversity branches, a relaying apparatus for relaying a communications signal, and a radio terminal which is able to use an IP address associated with a home address to move between wireless zones which the communications nodes form. The relaying apparatus includes a transmitting unit that transmits a received communications signal destined for the IP address, based on an instruction signal generated in response to a request of the radio terminal for site diversity, to at least two communications nodes including a communications node indicated in the instruction signal. The at least two communications nodes include a transmitting unit that transmits the communications signal to the radio terminal, and the radio terminal includes a receiving unit that receives the communications signal from each communications node.
